Om Mani Padme Hum is the mantra of Buddha Avalokiteshvara, also known as Buddha Kwan Yin. The repetition of this mantra brings down blessings and divine energy or spiritual energy from the Buddha of Mercy and Compassion.
When chanting Om Mani Padme Hum, all higher, ordinary, and lower sentient beings within a certain range will be, to certain degree, purified and healed. It also serves to soothe suffering, discomfort, and pain.
The person reciting this mantra, other people, and sentient beings around those chanting, will experience increased calmness and inner peace. Om Mani Padme Hum is indeed a mantra of mercy of compassion.
In this never-before-released version of Om Mani Padme Hum (Song), Master Choa Kok Sui sings instead of chanting this well-known mantra, giving the mantra an even softer, more loving feel.
